1.1 Provide your student profile (before or after workshop)

Please provide all the information requested on the page linked below:

https://rsm-compute-01.ucsd.edu:4443/rady-profiles/

To login, provide the first part of your @ucsd.edu email (NOT your @rady.ucsd.edu email). The password is the same one you use to access your UCSD email. Once you have logged on, “Profile Submission Form” in the navigation bar and complete the form. You don’t have to complete everything in one go, however. You can revisit the page and udpate your information any time.

1.2 Store this HTML file on your Desktop (before workshop)

Please save this HTML file to your Desktop. After the workshop move the file to a location you can remember as you will likely need to access it frequently over time.

You can get this HTML file, a PDF of the slides, and the other files we will use during the ICT session from the link below:

https://github.com/rsm-msba-24-25/rsm-ict-2024/archive/refs/heads/main.zip

For the ICT, please have both the links HTML file and the PDF of the slides open.

Note: On Windows it is important that you “extract” or fully unzip this file.

1.3 Install the Zoom app on our computer (before workshop)

Note: This section is relevant for Part-time FW MSBA students only

You must have the zoom app installed on your computer to have access to all relevant features (i.e., don’t use Zoom through your browser).

https://ucsd.zoom.us/download

Click the link below to claim your UC San Diego Zoom Pro account using Single Sign-On (SSO).

https://ucsd.zoom.us/signin

The ICT workshop is in-person. If you must join remotely (FW-MSBA only), and this is your first experience with zoom for a class or workshop, please review the linked document below so you are comfortable in this environment:

https://bit.ly/3mcAI0L

Two key issues if you are joining a class through zoom:

  1. You must have a working webcam so you can you have your video on and everyone in the classroom can see you
  2. Make sure to use a virtual background (see the zoom tutorial page)

1.4 Install the iClicker Student app on your phone (before workshop)

The iClicker Student app is created by HPHLP. You should create an account through the link below:

cp -p ~/git/docker/launch-rsm-msba-intel.sh ~/Desktop/launch-rsm-msba.command;
~/Desktop/launch-rsm-msba.command;

3.1.1 Automatically start Docker (before or during workshop)

You will want the Docker Desktop application to start up automatically. Click on the docker icon in the system tray (top right for macOS and bottom right for Windows), then go to Settings and copy the setting from the screenshot below.

3.1.2 Update Docker resource setting on macOS (before or during workshop)

You should change the (maximum) resources docker is allowed to use on your system. We recommend you set this to approximately 50% of the maximum available on your system.

3.1.3 Update Docker Advanced Settings on macOS (before or during workshop)

On macOS you may need to change a setting so that the Docker Command Line Interface (CLI) tools are available at the System level. See the screenshot below for the settings you should use.

3.2 Trouble shooting VPN on Windows

Check if you have internet connection from an Ubuntu terminal on Windows using the command below. If the printed output includes HTTP 200 you are fine.

curl -I https://www.google.com

If you have issues connecting to the internet from an Ubuntu terminal when VPN is on you can check the “Allow local (LAN) access when using VPN” box in Cisco VPN > Settings > Preferences as shown in the screenshot below

3.3 Setting up your terminal (before or during workshop)

If you want to use nicer fonts and icons in your terminal, follow the linked instructions to install the Meslo Nerd Fonts.

Download the four font files: * MesloLGS NF Regular * MesloLGS NF Bold * MesloLGS NF Italic * MesloLGS NF Bold Italic

Double-click on each file after downloading and click “Install”. This will make MesloLGS NF font available to all applications on your system.

On macOS install iTerm2 (https://iterm2.com/) and add it to the dock so you can easily access it in the future. Open iterm2 and make it your default terminal as shown in the screenshot below.

To change the font and icons:

iTerm2: Preferences → Profiles → Text and set Font to “MesloLGS NF”

On Windows open Windows Terminal to customize it. To change settings press CTRL + , and then first make Windows Terminal your Default terminal application and Ubuntu (22.04) your Default profile as shown in the screenshot below.

Next, click on the Ubuntu 22.04 icon on the left navigation menu and the starting directory is set to ~ as in the screenshot below.

Next, scroll down in Ubuntu (22.04) settings and click on Appearance. In the window that appears, set the font face to MesloGS NF. See screenshot below.

To finalize the docker setup we will configure the terminal “inside” the docker container available through the Launch Menu. Start the docker container, and press 5 + Enter to open a terminal. Press q + Enter, when prompted and then run the code below in the same terminal:

setup;
exit;

This can take a few minutes to run. When completed type exit and the press 5 + Enter again to open a new terminal.

Note: The new fonts may not show up right away. Is so try restarting your computer after the session.

For additional details see the page linked below (after workshop):

See slide deck shared for the ICT session

6 VS Code

6.1 Setup VSCode on your local system (during workshop)

Microsoft’s open-source integrated development environment (IDE), VS Code or Visual Studio Code, was the most popular development environment based on a recent Stack Overflow developer survey. VS Code is widely used by Google developers and is the default development environment at Facebook.

VS Code can be installed from the link below and is an excellent, and very popular, editor for Python, R, and many other programming languages.

https://code.visualstudio.com/download

6.1.1 macOS

Open VS Code and press Shift + CMD + P and type “shell” in the input windows that opens. Then click on “Shell Command: Install ‘code’ command in PATH”

Run the code below from a terminal on macOS after installing VS Code to install relevant extensions:

cd ~/git/docker/vscode;
./extension-install.sh;
cd -;

See this link for more information

6.1.2 Windows

Run the code below from a PowerShell terminal after installing VS Code to install relevant extensions:

Invoke-WebRequest -Uri https://raw.githubusercontent.com/radiant-rstats/docker/master/vscode/extensions.txt -OutFile extensions.txt;
cat extensions.txt |% { code --install-extension $_ --force};
del extensions.txt;

See this link for more information

6.2 The command palette

On macOS, press Shift + CMD + P, and on Windows, press Shift + CTRL + P to open the Command Palette. The palette is used to search for and execute most commands. For example, type “Jupyter” and you will seen an option to create an new Jupyter notebook. Type “folder” and then select “File: Open Folder” to navigate to the project folder you want to use. Type “quarto” to render a Quarto file to HTML and type “rmd” to render an Rmarkdown file to HTML. Type “preferences” to change your user preference settings. Etc. etc.

6.3 Attaching VS Code to a running container

Start the docker container as usual. Now start VS Code and click on the Green >< sign on the bottom left of your screen. Click “Attach to Running Container”.

In the window that opens at the top of the screen, select (1) /rsm-msba-arm on macOS M1, M2, or M3 and ARM-based Windows laptops or (2) rsm-msba-intel for all other computers.

Press Shift + CTRL (CMD) + P to open the Command Palette and type “folder” and then select “File: Open Folder” to navigate to the project folder you want to use and then click on OK. Do NOT click on “Show Local” as that will take you out of the container.

When you execute code in Python you will be asked to select a “Kernel”. Choose the “base” kernel (Python 3.11.9). Now VS Code has direct access to all the tools built into the docker container.

6.4 VS Code resources

See also the resources listed in the install instructions for the RSM-MSBA docker image:

https://github.com/radiant-rstats/docker/blob/master/install/rsm-msba-macos-m1.md#using-vs-code

7 Using the RSM-MSBA (ARM or INTEL) docker container

7.1 Starting the RSM-MSBA computing environment

The easiest way to start the docker container is to double click the launch icon that was added to your desktop during the install process.

Windows (Intel):

On Windows machines with an Intel chip your launch icon will be called launch-rsm-msba.bat. If you do not have a file called launch-rsm-msba.bat on your Desktop, you can create one by copy-and-pasting the code below in to a text file using notepad or VS Code. The pause line can be removed later if all works well. Open VS Code or notepad, copy-and-paste the code below into the editor, and save the file as launch-rsm-msba.bat to your Desktop. After saving, double-click the file on your desktop to get started.

# for a Windows laptop with an Intel chip use the below
wt.exe wsl.exe ~/git/docker/launch-rsm-msba-intel.sh -v ~;
pause;

In additional to the launch icon you can always start the docker container by running the command below in an Ubuntu terminal:

# for a Windows laptop with an Intel chip use the below
~/git/docker/launch-rsm-msba-intel.sh -v ~;

Windows (ARM):

On Windows machines with an ARM processor your launch icon will be called launch-rsm-msba.bat. If you do not have a file called launch-rsm-msba.bat on your Desktop, you can create one by copy-and-pasting the code below in to a text file using notepad or VS Code. The pause line can be removed later if all works well. Open VS Code or notepad, copy-and-paste the code below into the editor, and save the file as launch-rsm-msba.bat to your Desktop. After saving, double-click the file on your desktop to get started.

wt.exe wsl.exe ~/git/docker/launch-rsm-msba-arm.sh -v ~;
pause;

In additional to the launch icon you can always start the docker container by running the command below in an Ubuntu terminal:

~/git/docker/launch-rsm-msba-arm.sh -v ~;

macOS (ARM: M1, M2, or M3):

If you do not have a file called launch-rsm-msba.command on your Desktop, you can create one by running the code below from a macOS terminal:

cp -p ~/git/docker/launch-rsm-msba-arm.sh ~/Desktop/launch-rsm-msba.command;

In additional to the launch icon you can always start the docker container by running the command below in a macOS terminal:

~/git/docker/launch-rsm-msba-arm.sh -v ~;

macOS (Intel):

If you do not have a file called launch-rsm-msba.command on your Desktop, you can create one by running the code below from a macOS terminal:

cp -p ~/git/docker/launch-rsm-msba-intel.sh ~/Desktop/launch-rsm-msba.command;

In additional to the launch icon you can always start the docker container by running the command below in a macOS terminal:

~/git/docker/launch-rsm-msba-intel.sh -v ~;

7.2 Using Jupyter Notebooks in VS Code (during workshop)

See the slides that will be shared for the ICT session

Copy-and-paste the command below into a terminal in VS Code to get materials for the ICT session. Running the command will create a folder rsm-ict-2024 in your home directory.

usethis "rsm-ict-2024" --dest ~ "https://www.dropbox.com/scl/fo/sjsvs254egy8w94by092y/APElubXIZ64-XnbREdf7Ti8?rlkey=tqu21wexu6ir8e9d9hur50fyg&dl=1"

8 Where is my Data?

8.1 Accessing files from macOS

Open a Finder windows and navigate to your home directory. There should be a directory rsm-ict-2024 that we downloaded earlier (see screenshot below).

8.2 Accessing files from Windows

In an Ubuntu terminal, copy the code below

cd ~
explorer.exe ..

This will open a file explorer window. Right-click on your username and select “Pin to quick access” to make accessing files easier from both Windows and the docker container. See screenshot below.

8.3 Absolute and Relative paths

See the slides that will be shared for the ICT session

9 Connecting to PostgreSQL (aka postgres)

9.1 Accessing Postgres from Jupyter (during workshop)

Start the docker container and create a new Jupyter Notebook in VS Code. From the Jupyter Notebook run:

from sqlalchemy import create_engine, inspect, text
import pandas as pd

## connecting to the rsm-docker database
engine = create_engine('postgresql://jovyan:postgres@127.0.0.1:8765/rsm-docker')

## add a table to the database
with engine.connect() as con:
    con.execution_options(isolation_level="AUTOCOMMIT")
    con.execute(text("CREATE TABLE IF NOT EXISTS films (title text, director text, year text)"))
    con.execute(text("INSERT INTO films (title, director, year) VALUES ('Thor: Love and Thunder', 'Taika Waititi', '2022')"))

df = pd.read_sql_query('SELECT * FROM films', con=engine.connect())
df

9.2 Accessing Postgres from pgweb (during workshop)

Start pgweb and enter the code below in the “Scheme” tab:

postgresql://jovyan:postgres@127.0.0.1:8765/rsm-docker

9.3 Accessing Postgres from VS Code (during workshop)

Start VS Code and click on the icon with the elephant in the left navigation bar. If you don’t see it, click on “…” in the left navigation bar and select “PostgreSQL Explorer”. The elephant icon should now be visible. Next, click on the + in top left of your VS Code window to Add Database Connection. Use:

  • 127.0.0.1 as the hostname
  • “jovyan” as the PostgreSQL user
  • “postgres” as the password
  • 8765 as the port number
  • Standard connection
  • “rsm-docker” as the database
  • “rsm-docker” as the display name

If there are no error messages, you successfully connected to the postgres server that is included in the docker container. See also the install instructions for the rsm-jupyter container linked above. You may not have any tables in your database (yet) so you may see printed information that the database is empty (i.e., “character(0)”).

See the YouTube video linked below for a introduction to the Postgres extension in VS Code:

https://www.youtube.com/watch?v=Cc9d2c8UuKA

See link below for more detailed examples on using postgres with Python:

Trouble shooting

If there is a connection issue, there is most likely a problem with the docker volume that contains the databases. Stop the docker container by pressing q + Enter in the launch menu and then copy the code below into an Ubuntu or macOS terminal and press Enter.

docker volume rm pg_data

Now start the docker container again and try the steps above to connect to the database again. If you continue to have issues, post to the Rady499 piazza site.

9.4 Adding Databases for the SQL class (during workshop)

Run the below from a terminal in Jupyter Lab to add databases:

source <(curl -s https://raw.githubusercontent.com/radiant-rstats/docker/master/postgres/postgres-createdb.sh)

To take a look at what this script does click on the link below:

https://raw.githubusercontent.com/radiant-rstats/docker/master/postgres/postgres-createdb.sh

To double check you have access to both databases that were added, start pgweb and enter the code below in the “Scheme” tab:

Northwind database:

postgresql://jovyan:postgres@127.0.0.1:8765/Northwind

WestCoastImporters database:

postgresql://jovyan:postgres@127.0.0.1:8765/WestCoastImporters

9.5 Adding Connections to the new databases in VS Code (during workshop)

Now lets add VSCode connections for the databases that you will use in the SQL + ETL class. Make the postgres extension visible (see above) and click on the + icon to add connections. Use:

  • 127.0.0.1 as the hostname
  • “jovyan” as the PostgreSQL user
  • “postgres” as the password
  • 8765 as the port number
  • Standard connection
  • “Northwind” as the database
  • “Northwind” as the display name

Click on the + icon one more time to add the final connection. Use:

  • 127.0.0.1 as the hostname
  • “jovyan” as the PostgreSQL user
  • “postgres” as the password
  • 8765 as the port number
  • Standard connection
  • “WestCoastImporters” as the database
  • “WestCoastImporters” as the display name

Trouble shooting

If you are getting a “password” error on macOS, look for keychain access on your Mac and then for ckolkman.vscode-postgres. Delete the entry for this app and then uninstall and re-install the Postgres extension in VS Code. You should now see the connections to databases that you created earlier. If these connections do not give you access to these databases, remove them and then re-create the connections.

10 Git and GitHub for version control

10.1 Create an account on GitHub (before or during workshop)

Visit the links below to signup for a student GitHub account.

Provide the information below to set up your account. Your accout name must use the format below:

  • Email: Use your @ucsd.edu email address to qualify for a student account
  • Password: Choose a strong password that you can remember
  • Username: The format must be rsm-xyz123 where you replace xyz123 with the first part of your @ucsd.edu email address

The result would look something like the below. Follow the sign-up process, making sure to sign up as a STUDENT so you will get access to tools like GitHub Copilot for free.

10.2 Signup for access to GitHub Copilot

When you sign up for GitHub as a student you can get free access to Copilot. Make sure to take advantage of this offer.

Augie Donovan’s (FW MSBA 23-24) video on the process: https://www.youtube.com/watch?v=-ZvKRkxaOlQ

10.3 Why use Git and GitHub?

See the slides that will be shared for the ICT session

10.4 Introduce yourself to Git using GitGadget (during workshop)

Start a terminal on macOS or an Ubuntu terminal on Windows and run the code below to ensure you have full access to the directory where new settings and packages will be stored. When asked for your password provide the password for your computer. Note: It may not seem like what you are typing is getting through but it is, eventhough the cursor doesn’t seem to move.

sudo chown -R `whoami`:admin /usr/local/bin
sudo chmod -R 755 ~/.rsm-msba

Press (4 + Enter) from the Launch Menu to start GitGadget. Enter you UCSD username and email. The Server API should be set to: https://api.github.com/.

Make sure your User type is set to student and that the Base directory is set to ~/git. Get a GitHub access token through the link below or by clicking the “Create” button in the “Introduce” tab in GitGadget.

https://github.com/settings/tokens/new?scopes=repo,workflow&description=RSM-MSBA

It is important that you set Expiration to “No Expiration”. You can delete the access token after you graduate from the MSBA program.

After creating your token and introducing yourself to git by clicking the “Introduce” button in GitGadget, you can access the token by running the command below by launch a terminal (5 + Enter) from the launch menu to print the content of the ~/.Renviron file:

cat ~/.Renviron

The content of .Renviron should look similar to the screenshot below:

Your GitHub token should also have been added to your .zshrc file. Check this using the command below from a terminal (5 + Enter):

cat ~/.rsm-msba/zsh/.zshrc

At the end of the printed file, you should see something similar to the below:

export GITHUB_PAT="ghp_123abc123ABC"

If you type the below into a terminal (5 + Enter) you should see the printed token value returned as well.

echo $GITHUB_PAT

After setup, GitGadget should look similar to the screenshot below, expect that vnijs should be replaced by the first part part of your @ucsd.edu email:

Next, click on the SSH key button and copy-and-paste the key, i.e., a loooooooong sequence of letters and numbers, shown at the bottom of the GitGadget window (note: you may need to scroll down and/or to the right to get the whole sequence) to the GitHub page that was automatically opened in a new tab in your default browser.

https://github.com/settings/ssh/new

Now lets restart the docker container to see if all changes are being picked up. Close the browser windows with JupyterLab and GitGadget and then find the terminal window with the launch menu. Click in the launch menu window and then press (q + Enter) to stop the container. Then start it back up again through the launcher icon on your Desktop or by using the command below from a terminal on your host sytem (i.e., Ubuntu on Windows or the terminal application or iTerm2 on macOS)

macOS (ARM: M1, M2, or M3) and Windows (ARM)

~/git/docker/launch-rsm-msba-arm.sh -v ~

macOS (Intel) and Windows (Intel)

~/git/docker/launch-rsm-msba-intel.sh -v ~

Cloning your first repo

Start by creating a new repo on GitHub (https://github.com). The first time you clone a project from GitHub on a computer you should do it using a terminal because it will prompt you to confirm if you want to create a connection between your computer and the GitHub server. If your first repo on GitHub was labeled test1, then you could use the code below to clone your first repo, after changing the username.

mkdir ~/git;
cd ~/git;
git clone git@github.com:your-id/test1.git;
ls -l test1/;
rm -rf ~/git/test1;

If the code above ran without errors then you can use GitGadget or the Git and GitLens tools in VS Code to clone repos from now on.

10.6 How fix a merge conflict

See the slides that will be shared for the ICT session.

Fork the repo linked below to your personal account on GitHub. Then clone it to your ~/git/ folder using VS Code.

https://github.com/rady-ucsd/rsm-merge-conflict-practice

11 ChatGPT

You will need access to ChatGPT with Code Interpreter (Advanced Data Analysis Module) for the duration of the MSBA program. See the slides that will be shared for the ICT session for details.

12 Rstudio

12.1 Introduction to Rstudio (any time)

13 Installing Python and R packages

13.1 Installing python packages (during workshop)

Installing python packages using pip

We recommend using pip (or poetry) to install any additional packages you might need that are not already available in the RSM-MSBA docker container. Use the syntax below:

pip install --user --upgrade pyrsm"

pip is the package management command. install tells pip what you want to do and --user tells pip that you want to install this just for yourself in your home directory. This part is important if you want the package to remain available after restarting the docker container. The --upgrade argument ensure you get the latest possible version of the package you want to install. Finally, pyrsm is the name of a python package that is available on PiPy

To remove packages installed using pip, use the below and enter “y” when prompted to confirm you want to remove the package:

pip uninstall xyz

Removing locally installed packages

To remove locally installed R packages press 8 (+ Enter) in the launch menu and follow the prompts. To remove locally installed Python modules press 9 (+ Enter) in the launch menu.

13.2 Installing R packages (during workshop)

To install the latest version of R-packages you need, add the lines of code shown below to ~/.Rprofile or copy-and-paste the lines into an R notebook.

if (Sys.info()["sysname"] == "Linux") {
  options(repos = c(
    RSPM = "https://packagemanager.posit.co/cran/__linux__/jammy/latest",
    CRAN = "https://cloud.r-project.org"
  ))
} else {
  options(repos = c(
    CRAN = "https://cloud.r-project.org"
  ))
}

This will be done for you automatically if you run the setup; exit; commands from a terminal inside the docker container. To install R packages that will persist after restarting the docker container, enter code like the below in R and follow any prompts. After doing this once, you can use install.packages("some-other-package") in the future.

Lets first check the output from the command below in R:

.libPaths()
## create user directory
fs::dir_create(Sys.getenv("R_LIBS_USER"), recurse = TRUE)

## install a package
install.packages("fortunes", lib = Sys.getenv("R_LIBS_USER"))
fortunes::fortune()

## remove the package again
remove.packages("fortunes", lib = Sys.getenv("R_LIBS_USER"))

13.3 Removing packages

Use 8 + Enter and 9 + Enter from the launch menu to remove packages you installed.
